From performing in a show to operating a light board, student theater involves dedication, patience and a massive time commitment. Many high school seniors would not attempt to tackle the demands of nightly rehearsals and a grueling production week in addition to college admissions and exams. Many also never would dream of operating a theater company that produces multiple shows a year. But not the members of One Song. The local student-run theater group has been doing it for a while and will continue its work Sunday at the ArtsCenter in Carrboro.
